Why Do I Need Underlayments?
Underlayment is an amazing invention created by the flooring gods out of necessity. Underlay has an impressive list of benefits, including: adding warmth to your floors so your feet aren’t so cold on new tile flooring, adding comfort and a slight ‘give’ underneath wood or vinyl floors, reduced sound transmission (great for houses with noisy teenagers!), as well as reducing in room step noise. This image is a very simplified example of using underlayment versus not using it, but as you can see the benefits greatly outweigh any reason not to.
IIC / STC RATINGS
IIC stands for Impact Insulation Class, which refers to impact sounds such as shoes hitting the ground, dropping a cell phone, or other scenarios where something it dropped or impacts the floor. STC stands for Sound Transmission Class, which refers to any audible noise (not an impact) such as music playing aloud, a conversation, or a loud television, for example. With both of these ratings systems, the higher the number rating is for the underlayment, the better it will suppress sound, and the quieter a room will be. You may want to pay close attention to these ratings when shopping for underlayment if sound reduction is important to you.

Cork underlayment is one of the most common underlays used in condos, apartments and high rise buildings. Cork underlay has great thermal properties and is mold and mildew resistant. Rolled cork underlayment is great under all flooring types and can be installed at or above grade in your home. Cork is very easy to install, but should not be nailed or stapled. Cork will expand and contract with your floor and also aides in preventing crack formation in your floor. A vapor barrier is typically necessary with this acoustical underlayment in areas where moisture may be an issue.
